Local area network-based geophysical logging real-time quality monitoring device

Abstract

The invention discloses a local area network-based geophysical logging real-time quality monitoring device. The local area network-based geophysical logging real-time quality monitoring device comprises a top plate arranged on the upper side of a well logging, a motor is fixedly arranged on the top plate, a mounting seat is rotatably arranged on the lower wall of the top plate, the mounting seat rotatably penetrates through the top plate and is fixedly connected with the output end of the motor, a threaded rod is fixedly arranged on the mounting seat, the threaded rod is fixedly arranged on the mounting seat through a fixing mechanism, the threaded rod is rotationally sleeved with a lantern ring, and a threaded through hole corresponding to the threaded rod is formed in the lantern ring. The threaded rods with different lengths can be rapidly replaced according to the depth of a well logging, the adaptability of the device is greatly improved, the monitoring device can automatically stop descending after reaching the water in the well logging and can automatically follow the water level to descend when the water level in the well logging descends, it is guaranteed that the monitoring device always monitors the water pressure and water quality in the well logging underwater, the problem that the water level decline, the monitoring device is exposed out of the water surface, and the monitoring is difficult to conducted is avoided.

Description

technical field [0001] The invention relates to the technical field of well logging monitoring, in particular to a real-time quality monitoring device for geophysical well logging based on a local area network. Background technique [0002] Geophysical logging is referred to as logging for short. In the process of exploration and exploitation of oil, coal and metal ore bodies, various instruments are used to measure the physical parameters of the downhole rock formation and the technical status of the well, analyze the recorded data, and carry out geological and engineering aspects of research. According to the physical basis of logging methods, there are mainly electrical logging, radioactive logging, acoustic logging, and formation dip logging. In oil and gas field logging, logging data are mainly used to determine important parameters such as reservoir porosity, oil saturation, and permeability; To provide basis for formulating development plans; use logging, geology, g...

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings in the prior art, such as: traditional logging monitoring equipment has poor adaptability, it is difficult to adapt to logging at different depths, and during the monitoring process, the water level in the logging will often cause monitoring The instrument is exposed to the water surface, which affects the follow-up monitoring, and a real-time quality monitoring device for geophysical logging based on LAN is proposed
